DRAFT-RIGGING.

sPECIFCATON forming part of Letters Patent No. 740,779, dated October 6, 1903. Application iiled March 30, 1908. Serial No. 150,264i (No model.)

To a/ZZ whom, t may concern:

Be it known that'I, HERMAN C. PRIEBE, a citizen of the United States, residing at Bradford, in the county of Stark and State of Illinois, have invented a new and useful Improvement in Draft-Riggings, of which the following is a specification. Y

My object is to provide a draft-rigging adapted more especially for freightcars and of an im proved construction which renders it particularly simple, strong, and durable and well adapted for all requirements, also easy' to place in position and to inspect.

Referring to the drawings, Figure 1 is a broken plan sectional view of my improved draft-rigging at one end of a car, the springs at one side being shown in elevation and those at the opposite side in section; and Fig. 2, a broken partly-sectional side elevation.-

For convenience l show my improvements applied to a car of steel construction, though the invention is not to be limited thereto.

.A indicates one of the end sills of a freightcar, and B B longitudinally-extending center sills. These center sills in the construction shown are steel channel-beams, as is usual in steel constructions, and form in themselves the draft-plates. Riveted, preferably, against the outer faces of the center sills in the channels thereof are reinforcingplates C C of desired.v length. Extending through the center sills and their reinforcingplates in the positions shown are forward slots d and rear slots b, elongated in the direction longitudinally ofthe sills.

D is a draw-bar havlng aneckv portion D', Y

movable in the usual way through a sustaining-guide in the end sill A, and a stem-portion D2.

4o rear openings c d, corresponding in size ap'- 5o sides of the sills C and having looped ends e,

arranged to fit over the end portions of the bars E F. Between the coiled portions of the In vthe stem portion are the forward and said springs andthe bars or followers E F are preferablyV flanged 'orpcupshaped, disks or the end portions of the springs'j pass, lwhich operate to maintain 'the disks or washers in place. Between the disks or washers f at each side are outer coiled springs H, confined at their endsinthe cups afforded by the disks. The springs are held against removal by cotters or the like g passing through the bars, as shown. The springs H Gr fit tightly between the disks or washersfandoperate normally. to maintain the bar E at the forward ends of the slots a c and the. bar F atl the rear ends of the slots h d.

A pull upon the draw-bar D causes it to bear against the rear bar F and compress the springs'against the bar E, which remains stationary, while the draw-bar may travel forward a distance equal to the length of the slots c b. Backward pressure against the draw-head causes the draw-bar to bear against the forward bar or follower E and force it backward in the slots d to compress the springs. ln this movement of the draw-bar the follower E moves in the slots a, while rthe bar F remains stationary, permitting the draw-bar to move in the backward direction a distance equal to the length of the slots d a.

The plates C operate to reinforce the sills at the slots. It will be seen that the parts are so arranged that they may be readily placed in position or removed. The springs G H are in exposed positions,so that they may be readily/inspected, and inV the event" that .one of them becomes broken it is an easy matter to removethe cotters g,slip the springs from the followers, and replace with new springs. The construction permits the employment of a very strong and durable drawbar, and the pull thereon is resisted by the followers E F, which, being placed to resist the strain edgewise, are especially strong. When the movement of the draw-bar proboth the followers rest against rigid stops at the ends of the slots a b, and thus they both operate to resist the strain. rlhe draw-bar vtherefore cannot be drawn out or displaced, even in the event that the springs' or `one of the followers shouldbe broken.

It is desirable to have the draft-plates or washersf, having perforations through which l duces complete compression of the springs they may be variously modified in the matter of details without departing from the spirit of my invention as defined bythe claims.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a draft-rigging, the combination of draft-plates having elongated forward and rear openings, a draw-bar having a solid integralstem portion provided with forward and rear openings corresponding with said openings in the draft-plates, forward and rear follower-bars extending through the said forward and rear openings in the draw-bar and draft-plates to slide therein in the direction longitudinally of the car, and coiled springs confined between and bearing at the opposite ends of their coils against said follower-bars at the outer sides of the draft-plates.

2. In a draft-rigging, the combination of draft-plates having elongated forward and rear openings, a draw-bar having a solid integral stem portion provided with forward and rear openings corresponding with said openings in the draft-plates, forward and rear follower-bars extending through the said forward land rear openings in the draw-bar and draft-plates to slide therein in the direction longitudinally of the car, and coiled springs confined between and bearing at the opposite ends of their coils against said follower-bars at the outer sides of the draft-plates and removably connected at thei ropposite ends with the follower-bars.

3. In a draft-rigging, the combination of draft-plates having forward and rear openings, a draw-bar presenting corresponding forward and rear openings, follower-bars eX- tending through the said forward and rear openings in the draw-bar and draft-plates to slide therein in the direction longitudinally of the car, coiled springs confined between the said follower-bars at the outer sides of the draft-plates and having looped lends fitting over said bars and removable pins extending through openings in the end portions of the follower-bars for holding the springs in place.

4. In a draft-rigging, the combination of draft-plates having forward and rear openings, a draw-bar presenting corresponding forward and rear openings, follower-bars eX- tending through the said forward and rear openings inthe draw-bar and draft-plates to slide therein in the direction longitudinally of the car, inner coiled springs between said follower-bars at the outer sides of the draft- .plates having looped ends fitting over said follower-bars, removable pins confining the said looped ends against sliding from the follower-bars, washers upon the said looped end' HERMAN C. PRIEBE.
